crnn PAPER.

T 0 all whom it may concern:

Be it known that we, Jorm D. 'Ionrrmns and Fnannmcn H. FULLER, ofValatie, in the county of Columbia, and in the State of New York, andPotsdam, county of St. Lawrence, and State of New York, respectively,have invented a certain ment in Crimped Paper, and do here y declarethat the following is a full, clear, and exact description thereof.

Our invention relates particularly to the production of a crimpedadvantages and improved characteristics over crimped papers previouslyused.

The object of our invention is to provide a crimped paper which willhold the crimping better and for a longer period under the many uses towhich crimped paper is applied, tolprovide a crimped paper which isstronger and tougher and more durable than that hitherto produced, toprovide a crimped paper which is practicall lintless yet which is highlyabsorbent, whi has greater tensile strength than crimped paperspreviously produced, which is so made that the crimpmgs in the paperwill stand jars or strains much better than other crimped papers,'thusadapting the crimped paper particularly to use in stretchable paperbags, and which, because of its strength and softness is particularlyadapted for use as wrapping paper, such, for example, as wrapping paperfor glassware, bottles, etc.

' Our invention comprises in general a crimped paper which has beengiven its crimping while heated and in a moist condition in such amanner that a portion of the surface of the web of, paper is iven adistinct glaze, the glaze being re erably' roduced on'the entire surface0 one side 0 the web of paper, and the web of paper being formed withcompressed areas extending along the web of paper to form por tionsthereof having greater compactness, strength, etc. v 7 As oneillustrative manner in which the paper made in accordance with ourinvention may be produced, a moist web of paper is conducted over aheated roll which will give to the surface of the web next to the 1 rolla distinct glaze. While on the roll the aper is subjected tocompression, as by pr ucin water marks, by the web being conducted upona heated roll beneath a Specification of Letters Patent.

weighted roll or equivalent means for compressing certain portions ofthe web of paper. The web of paper is thereafter removed from the heatedroll b plate which crimps the web of paper while eated and in a moistcondition. The paper is then dried in any suitable manner.

In the accompanying drawings we have shown an apparatus in which crimpedpain accordance with our invention, and a form of the completed productmade therein.

In the drawings Figure 1 represents a cross-section of an apparatus usedfor formpaper, shown diagrammatically; and, Fig. 2 is a plan view of aportion of a web of paper made in accordance with our invention.

This apparatus comprises a heating roll 1, over which is conducted a webof paper 2 in a moist condition. The web of paper 2 is conveyed while onthe roll 1, beneath a presser roll 3 having one or more annularprojections 4, although it is to be understood that the projections maybe of any desired shape. Thereafter, the paper, While still heated andin a moist condition,-comes in contact with the blunt edge of a crimpingplate 5 which crimps the web of paper and removes the same from thesurface of the roll-1 allowing it to fall and pass to any other desiredapparatus to dry the web of pa er. I

n Fig. 2 we have shown a form of the roduct produced in the apparatusshown in ig. 1, said product comprising a portion of a web of paper 6having a series of Iongitudinal compressed areas 7 extending along thebody of the web of paper. The product thus produced has one surface,that is to say, the surface which was located next to the heating roll,glazed to some extent, while the other surface may not be so glazed, andthe body of the paper provided with a series of compressed portions 7extending alongthe body thereof. The glazing and compression both impartgreat strength to the web of paper and maintain the crimped form of thepaper which has been given to the web of paper while in the heated,moist condition. The paper stock being usually produced from Wood fibersor other constituents, of which cellulose is the main element, thefibers retain the form y a crimping v tensile given to them by pressurewhile in a heated, moist condition, in the manner well known inconnection with treatment of all articles ofwood to which it is desiredto give a permanent set in a bent condition. Furthermore,'while a web ofpaper is thus produced having very great strength and toughness, and insuch a manner that it will tend to retain its crimping for a longer timethan was possible in the case of previous types of crimped paper, thepaper is, nevertheless, very absorbent, and thus may be used to greatadvantage as paper toweling and for all uses to which paper is appliedwhere it is necessary for the paper to be absorbent. Furthermore, theinfluence or production of the glaze on one surface extending quitethrough the body of the web of paper prevents the formation of lint uponthe surfaces of the web of paper, and thereby reduces,by at least onehalf, the tendency of the web of paper to form into lint when beingused. Again, the paper has such a great degree of strength and retainsits set so effi ciently that it is extremely well adapted for use forpaper bags and in every manner in which crimped paper is used wheregreat strength is desired. The great strength of the paper and thesoftness of the glazed surface particularly adapts it for wrapping andpacking glassware of all kinds.

While we have shown and described one form of our invention, we wish itto be understood that many changes may be made therein without departingfrom the spirit 0 our invention.

3. A sheet of paper crimped as a whole, having glazing on one surface,and having portions thereof of greater density than the remainderthereof, the folds of the crimping being retained in the originalelevated position in the glazed and more dense portions.

4. A sheet of paper crimped .as a whole and having continuous portionsthereofof reater density than the remainder thereof, the folds of thecrimping being retained in the original elevated position in the moredense portions. p

5. A sheet of paper crimped, having glazing on one surface, and havingcontinuous portions thereof of greater density than the remainderthereof, the folds of the crimping being retained in the originalelevated position in the glazed and more dense portions.
